Description
The MS24399D13 is a genuine Textron Aviation reducer tube precision type of a type generally used to route fluid, air, or wiring through the airframe. It fits the 1900 Airliner, 1900C Airliner, and 1900D Airliner. It carries an export classification of ECCN 9A991.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS24399D13 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Across the Beechcraft 1900 fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Because it handles pressurized fluid or air, a component like this is specified precisely for its service — the right part keeps the system sound. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean.
Beechcraft, founded in Wichita, Kansas in 1932, joined Cessna and Hawker under Textron Aviation in 2014, which today supports the worldwide Beechcraft fleet with genuine factory parts. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
